By choosing long-blooming perennial plants, you can capitalize on the best of both worlds – plants that come back from growing season to growing season, and those that bloom for an extended length of time. This also means you’ll have more time to appreciate the gardens you create!

Here is just a sampling of long-blooming perennial plants perfect for the sunny summer garden:

• Achillea (Yarrow) is a very drought and heat resistant plant once established. The flower heads are long-lasting and many colors are available including yellow, gold, pink and pastels in apricot, lilac, salmon, cream and white. Plants grow from 8-36″ tall, depending on variety. The flat-topped flower heads grow up to several inches across, and make excellent cut and dried flowers. The fern-like, gray to gray-green foliage is somewhat aromatic and attractive even when the plant is not in bloom.

• Coreopsis (Tickseed) is one of the easiest and most rewarding garden flowers. The thread leaf varieties are usually the longest blooming, typically from June through fall. The pale yellow, bright yellow or rosy-pink daisy flowers smother the slender stems and thread-like leaves. Plant height, from 15-24″, is variety dependent. A mid-summer shearing of the seed heads will keep these plants blooming for many more weeks.

• Echinacea purpurea (Purple Coneflower) is a sturdy, bold-textured favorite with dark foliage that grows to 2-3′ tall and wide. The flowers are large, daisy-like with unique standings of dark-rose purple and lighter in color. Birds and butterflies also love these flowers, adding even more beauty to your garden with their visits.

• Rudbeckia (Black-Eyed Susan) is an old-fashioned garden favorite. It is hardy, reliable, insect and disease-free and an exceptionally long-blooming plant – typically from July through fall. This medium-green, bold-foliaged plant grows to about 3′ tall and bears golden yellow, daisy-like flowers with dark brown centers. Both Echinacea and Rudbeckia flowers make excellent cut flowers and a wonderful place for butterflies to sit and eat.

• Gallardia (Blanket Flower) is an American native plant which thrives in the hot sun and has beautiful yellow-orange flowers, marked with red. Height varies according to variety. Some favorites include “Baby Cole” which is a dwarf only 8″ high, “Goblin,” a 12-15” grower, and “Burgundy,” which reaches 18-24” and whose flowers are a gorgeous shade of burgundy red.

• Ceratostigma plumbaginoides (Plumbago) features intense blue flowers from mid-summer to September. Plumbago spreads quickly to form a neat groundcover and as an added bonus, leaves turn a brilliant red in the fall before dropping. This excellent perennial grows well in light shade also.

• Veronica (Speedwell) has neat, attractive foliage and abundant flowers in densely packed spikes. Look for the cultivars ‘Goodness Grows’ and taller ‘Sunny Border Blue’ for a beautiful addition of blue to your summer garden, and pair it with red or white favorites for a patriotic theme.

Remember, this is just a brief glimpse of the long-blooming perennials available to choose from. Stop by to see our wide selection of perennials so we can help you determine which plants are best suited to your garden.

Continue planting trees, shrubs, perennials, annuals, vegetables and herbs. Consider adding some exotic color to your deck or patio with tropical blooming plants. We have a great selection of color this summer.

It’s time for your houseplant’s summer vacation! Take outside to a shady place. Repot if necessary, fertilize and check for pests and diseases. They’ll thrive in their outdoor location all summer. Be sure to bring them back inside in early fall.

Water plants and lawns deeply during periods of dry weather. Annuals, perennials, vegetables, trees and shrubs should be watered with a slow trickling or soaker hose. Pay extra attention to plants in containers and hanging baskets – check them regularly. Remember that clay pots dry out faster than plastic.

Apply a 2-3″ layer of mulch on your garden beds in preparation for summer. Mulch conserves valuable moisture in the soil, helps keep weeds down, maintains even soil temperatures, and gives an attractive finishing touch to your beds and borders.

Spray azaleas, Pieris japonica, laurel and Rhododendron with Bonide All-Season Oil to control lacebug. Spray early in the morning or evening when temperatures are moderate and there is no rain in the forecast.

Warm, humid weather encourages the development of fungal diseases such as Black Spot and Powdery Mildew on roses. Water roses in the early morning and avoid overhead watering if possible. Clean up any fallen leaves and follow a regular fungicide spray program. We recommend the Bayer Rose and Flower All in One for good control of fungus diseases.

Prune evergreens such as pines, cypress, hollies, euonymus and boxwood, to shape as needed. Remove faded flowers of annuals regularly, to encourage more flowers. Annuals will also benefit from regular applications of a water-soluble fertilizer right through summer.

Attract hummingbirds and butterflies to your landscape by planting Butterfly Bush, Bee Balm (Mondarda), Hardy Hibiscus, Lobelia, Scabiosa and Coreopsis.
